Chef Curtis Duffy will cook his final service at Avenues Saturday, and after that, the two-Michelin star flagship restaurant of The Peninsula Hotel will close indefinitely.

Avenues will be searching for a new chef de cuisine in the interim. According to a press release sent out, the hotel will also be "evaluating a concept change" and "the possibility of a renovation" in early 2012.

The restaurant space will be available for meetings and events, the release continued, and Peninsula wine director Michael Muser will be hosting a series of wine dinners in the coming months.

Duffy, as first reported in the Tribune, will be opening his own restaurant in the West Loop, scheduled for a 2012 opening. The 36-year-old Duffy was Alinea's original chef de cuisine, and also spent time at Charlie Trotter's and Trio.

"I want to have the best restaurant in the country," Duffy told the Tribune in July. "I want to obtain that third Michelin star."
